SPECIFICATION forming part of Letters Patent No. 388,019, dated August 21, 1888.

Application filed December 3, 1887. Serial No. 256,943. (No model.)

To all whom, it may concern:

Be it known that I, LOWELL J. BULLARD, a citizen ofthe United States, residing in the city, county, and State of New York, have in vented a new and useful Improvementiu Lamp or Burner Flame Extinguishers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,wherein similar letters refer to simi lar parts throughout the several views.

The principal object of my invention is to provide means of extinguishing the flame of a lamp or burner by mechanism. Incidental objects are to prevent the escape of smoke, volatile vapors, and unpleasant odors generated by a heated wick, consequent upon blowing out a lamp in the ordinary Way; also, to prevent evaporation when the wick is not ignited; also, to secure the greatest practicable space for the direct passage of the air-supply to the naine and to diminish lateral air-currents,aud thereby promote more efficient combustion by direct air-currents, to prevent the deposition of coke incrustations upon or around the hingejoints, and to provide an extinguishing device capable of attachment to ativicl; lamps and burners of separate manufacture, without necessitating the construction ofspecial lamps and burners for their employment. These objects I accomplish by my invention,which consistsin the mechanism hereinafter more fully set forth for intercepting and checking the ai r-currents at and around the point of combustion or inflammation sufficiently to effect extinction of the flame by means of inconibustible flaps, whose projecting edges are conjointly brought together by operative mechanism, so as to form an envelopingfchaniber over and around the upper parts of the Wick-tube.

In the accompanying drawings, Figure l is a plan View of the under side of an ordinary flat-wiel; lamp-burner, showing my lever attachments. Fig. 2 is an elevation of the same with portions thereof cut away to expose the lever and its connections with the flaps. Fig. 3 is a perspective view of the naps. Fig. 4 shows the positions ofthe lug or boss E and of the angular spring Lwhen the flaps are closed; and Fig. 5 shows the positions of the same parts when the flaps are open, and both such igures represent the manner of maintaining the flaps fully open or fully closed Without intervening points of rest.

A A are extinguishing-flaps; B, dome; G C, bifurcated lever; D D, links connecting same to flaps; E, detent-angle; I4, actuating-arm; G, pivot; H, base; I I, hingejoints; J, pintle; K, perforated gallery; L, detenta-spring; T, Wicktube; t, air-tube; YV, wick.

The liaps are preferably made of thin sheet metal and suitably shaped to forni, when their opposing edges are closed against each other Within the dome, close contacts over and at each side of the wick-tube, substantially forming a chamber over theiguited end of the wick-tube, and interceptingasupply otair to the amesufcient to extinguish it. They areboth hinged on opposite ends at points common to both, and affording sufticientscope of action to cause their upper edges to extend, when closed, slightly above the Wick in the Wick-tube, and to permit, when open, the convenient lighting of the Wick. In practice I locate the hingejoints at convenient opposite points near the angle formed by the Wick-tube with the perforated gallery at the short sides, and make the flaps of a height and Width sufficient to extend upward and inward and around, so that their edges form practically close contacts when closed above the median line ot' the wick and half-way around the top of the wick tube and in proximity to it on each side, so that they shall conjointly form a chamber inclosing the lighted portion of the wiel; and the upper parts of the Wick-tube. In order to permit of free circulation of air-currents when the deps are open, they may be cut away between the opposite hinges on the ends and sides for approximately half their height.

To operate the aps, they are connected at any convenient point, preferably at their backs, with links or tine bars D D, passing down through the perforated gallery, and there respectively movably attached to the arms of a bifurcated lever, G C, as shown in Figs. l and 2. These links or bars are preferably made of iine Wire, and are curved sufciently to admit of their action without unduly slotting or enlarging the perforations in the gallery.

The lever C C is pivoted at any convenient point Which will afford suiiicient play for opening and closing the flaps, but preferably near the outer edge of the base, as shown at G in ICO saaole the drawings; and in order that the position of the aps may not be accidentally disturbed the lever near the pivoting-point is formed to present an angular contact with a spring, as at L, also presenting to it a like contact, so that the lever is detained at one or the other side of such contact, as may be desired, while readily changeable from one position to the other by actuating the lever-arm F. In the drawings, Fig. l, the lever is open and eX- panded laterally, so as to secure greater breadth of pivotal bearing, and bears against the opposing projecting angular blade-spring L By depressing the lever-arm F the detentangle of the lever is caused to slip over the like opposing projection upon the spring, at the same time raising the extinguishing-flaps up against each other, so that their opposing edges meet at or about the vertical median line over the Wick and tube and partially down the short sides of the tube, and cut off the supply of air from the flame, which is thereby extinguished. v

The principal parts of my device are capable of being struck from sheet metal and advantageously attached to ordinary lamps and burners or oil-stoves by rivets, so that it is unnecessary to construct special burners for their employment.

Having described my invention, what I claim as new, and which I desire to secure by Letters Patent, is

1. In a dame-extinguishing device for lamps or burners, the flaps A A and the bifurcated lever C, provided with connectingrods D D and with a de tent angular boss or lug, E, and pivoted at the base to bear against an opposing angular spring, L, in combination with the spring L and a dome or bearer, and operative substantially as described. A

2. In a fiame-extinguishing device for lamps or burners,the flaps A A, terminally and pivotally connected together and attached to the perforated base at the narrow sides ofthe wick-tube at itsjunction with the gallery, in combination with the bi furcated lever O, provided with connecting-rods D D and with a detent angular boss or lug, E, and pivoted at tbe base and bearing against an opposing angular spring, L, and-53 with such spring L and a dome or burner, and constructed substantially as described.
